Those on the autistic spectrum, how do they process information?

Researchers who studied how we process information have found that dyslexics have difficulty learning from stimuli to which they were previously exposed, while those on the autistic spectrum use prior information but update it slowly

None of us sees the world as it really is.When we see, hear, or smell what is around us, we do not passively absorb the information that exists in the world: the moment it is absorbed by our senses, we process the information in part based on what we have seen,heard and smelled in the past. 

For example, when our dog runs to the end of the street, we realize that it will not get smaller just because it's getting less space on our retina now. 

Similarly, we do not think the red swing in the garden changed color on a cloudy day, although objectively, the wavelength it returns is different from the one it brought back when it was sunny. 

Different perceptual biases are built into the way we process information, allowing us to use a wider context to understan…

Rare microscopic creatures are genetically different from any of the other species known to science

Canadian researchers have found rare microscopic creatures that are genetically different from any of the other species known to science
Biologists use a method called systematics to classify living organisms into groups and explore their relationship. For example, the lions are species of the genus Panther, belonging to the cat family, belonging to the mammalian department, which belongs to the animal kingdom. 

The classification indicates a connection to a common ancestor and a level of "familial" closeness among various creatures, including those already extinct, and by means of which a sort of a family tree called "an evolutionary tree of life" is created. 

In the past, the classification was based on external characteristics such as appearance, but nowadays the classification is based primarily on genetic similarity in DNA.

A few years ago, Y. Eglit, a student from the University of Deliose, Canada, traveled across Nova Scotia and collected dirt from the area. Wh…

A new study found the same genetic signature associated with monogamy in species

Same genetic signature associated with monogamy in mammals, birds, amphibians and fish.
Monogamy evolved in many different groups of animals.Prairie voles, little rodents who live in North America, do not believe in free love. When they choose a partner, they stay with them for life, raise the offspring together and cooperate in preserving the territory. 

Monogamy is not unique to voles of course: we observe it in other mammals and also in birds, amphibians and even fish. It seems to have evolved again and again, independently, in different groups of animals. 

A new study suggests that in each such case, genes responsible for monogamous behavior were involved in the development of monogamous specie from an ancestor that wasn't monogamous.

A study compared monogamous animals to five non-monogamous animals.Researchers from universities in the United States and the United Kingdom compared five monogamous species to five non-monogamous species. 

For example, they examined the Meadow vole a…

Will aliens interpret the first message from humanity to them as a cyber attack?

This hypothetical issue was discussed at a conference held at the Bradford Science Festival, which dealt with the question of what message should be transmitted to aliens and whether we would be the initiators of the broadcast. 
The discussion was held with the aim of promoting the - http://breakthroughinitiatives.org project which offers $ 1 million to the best message provider. The competition is open to the general public.
The issues discussed at the Science Festival organized by the British Scientific Society, and was about formulating the first message for intelligent aliens and whether to launch it deliberately or merely to send it in response to a broadcast from an alien civilization.

The speakers at the event were members of the British branch of seti, who were competing for a $ 1 million prize from Russian Internet billionaire Yuri Milner as part of a larger $ 100 million project initiated by Russian billionaire Yuri Milner, in which Professor Stephen Hawking is also involved. 

IBM unveiled IBM Q System One at CES | First of its kind quantum computing system for scientific use

These systems were designed by IBM scientists, system engineers and industrial designers, enabling the first time to operate a computer based on quantum processing outside the research labs.

The computing power of quantum systems is immeasurably superior to the capabilities of classical computing systems and is designed to deal with problems that are too complex for today's computers. 

Applications of such systems may include complex problem solving related to molecular and chemical interactions, development of new drugs, new materials, financial modeling, risk management, or improvement of large systems.
Classic computers are built into a package that combines a large number of components into a single architecture. 

IBM has implemented a similar approach to quantum computing and IBM Q systems one combines thousands of components working together to offer the most advanced computing device of its kind operating in the cloud environment. 

It is one of the most sophisticated, modular a…

SpaceX wants to send three tourists to the ISS

The US space company SpaceX wants to send three tourists to the International Space Station ISS.



It is planned that the tourists will travel to the ISS in the second half of 2021 together with a commander in the "Crew Dragon" space capsule, as the Texas start-up Axiom - SpaceX's partner company in the project - announced on Thursday.Neither of the two companies gave any indication of how much the tourists would probably have to pay for the trip. 

The costs for the launch of the Falcon 9 rocket alone, which will transport the space capsule into space, amount to around 60 million dollars (53 million euros).

In addition, the construction of a new "Crew Dragon" capsule must be financed.

🔹 In this respect, the ticket for the flight should cost tens of millions of dollars.

In earlier years, a total of eight tourists had already travelled to the ISS in Russian Soyuz capsules. 

The first was US entrepreneur Dennis Tito in 2001, who paid 20 million dollars for a vacati…

A new species of insect was named after Lady Gaga for being eccentric. | Kaikaia gaga

Insect was named after Lady GagaBrendan Morris, PhD at the University of Illinois, observed the behavior of about a thousand treehoppers for his research project when he suddenly noticed one female who was different from the others.


Scientists decided to name the recently discovered insect in honor of Lady Gaga for their "eccentric sense of style," NME reports.

In the scientific publication Zootaxa, he and his co-author, the entomologist Christopher Dietrich, wrote about it "an additional cross m-cu (between the fourth and fifth longitudinal veins) in the front wing, as well as a frontal-clipella form".

Morris decided to call the insect "Kaikaia gaga" so that specialists could understand what kind of species we are talking about.

"If there ever is a Lady Gaga bug, it will definitely be a treehopper bug because of its crazy horns and eccentric sense of style. They don't look like anything you've seen before," he explained.

Now Morris hopes…

How the lungs of a person suffering from Coronavirus look | Photos

Chinese doctors have published an x-ray of the lungs of a patient with the coronavirus 2019-nCoV that has spread through China and other countries.

Scientists propose to fight viruses with fullerenes

Fight viruses with fullerenes
Scientists from Skoltech and the Institute of Problems of Chemical Physics of the Russian Academy of Sciences have created water-soluble fullerene compounds that have valuable biological properties. The results of the study are published in the journal Chemical Communications. Thanks to this biological properties they can be used to develop effective antiviral drugs, including to suppress the human immunodeficiency virus (HIV).

Fullerenes are molecular compounds composed of three-coordinated carbon atoms, which are closed convex polyhedra. Depending on the number of atoms in the molecule, fullerenes resemble a soccer ball (C 60 ) or a rugby ball (C 70 ) in shape.

Compounds based on fullerenes have a pronounced antiviral, antibacterial, antitumor and antioxidant activity, so scientists have long viewed them as a promising basis for the creation of new drugs. Unfortunately, fullerenes are absolutely insoluble in water, which prevents their use in medicine.

Medications have positive results in research for the treatment of coronavirus; here are 4 possibilities

Medicine used against malaria for almost 100 years and others without approval in Brazil are among the most promising after tests.


Four drugs showed positive - but still preliminary - results in scientific research in the treatment of Covid-19, a disease caused by the new coronavirus. These drugs act at different stages of cell contamination. They are:

ChloroquineRemindLopinavir/RitonavirFavipiravirHowever, self-medication is not recommended, since research has not been fully completed and it is not yet known whether there are any side effects from use by patients infected with the coronavirus.
The study on Favipiravir was released on Wednesday (18) - it is sold commercially in Japan under the name Avigan. It was developed by Toyama Chemical, of the Fujifilm group, and has been used for over 5 years against Influenza. Its use is only authorized in Japan.
The medicine is being tested only in laboratories outside the country. When consulted, Anvisa informed that there is no request for re…

What do dolphins and whales drink if there's only salt water around?

Have you ever wondered how dolphins and other marine mammals obtain fresh water when they have been in salty environments all their lives? 

They don't have a desalination unit like in the gills of marine fish, and their kidneys can't dissolve sedimentary minerals. What kind of trick did nature invent?They can't drink seawater: with dolphins and whales, nature played an evil joke. It would seem that they are surrounded by water, but the use of salt water, on the contrary, will lead to dehydration and death.
In the case of sea fish, part of the salt that comes with sea water into the body is desalinated in the gills, and the salty surpluses come out with urine.
The salty environment in which they live, constantly pulls moisture out of the fish through the skin. It's a natural process - osmosis.

Therefore, these sea creatures have to drink sea water all the time and the more salt they have in them, the more they have to drink.
Dolphins and whales can't do that. They have n…

A second case of a patient with HIV being cured is confirmed; he comes out of hiding.

So far he has been called a the "London patient", but the man decided to come out of the shadows and reveal his identity. A second case of full recovery from AIDS, but doctors warn of over optimism.
Scientists at the IrsiCaixa AIDS Research Institute have confirmed that the so-called London patient has been cured of HIV, the second in the world, because 29 months after undergoing a stem cell transplant and stopping taking antiretrovirals he is still without a trace of the virus.The study of the London patient, published this Tuesday in the magazine "The Lancet HIV", has coincided with the announcement of another patient, in this case from Düsseldorf (Germany), which, according to the scientists, could become the third case in history to be cured of HIV, after the London case and one in Berlin.

New online today—30 month follow-up of the London patient, providing further evidence that he is the second person to be cured of #HIV. The long-term follow-up provides insi…
